TVR14101 Metal Oxide Varistor

Description

The TVR 14101 is a Metal Oxide Varistor (MOV) used for surge suppression and voltage spike protection in electronic circuits. MOVs are widely used to protect against high-voltage transients such as lightning strikes, electrostatic discharges (ESD), and switching surges. MOVs work by clamping excessive voltage to a safe level when exposed to a transient voltage surge, thereby preventing damage to the electronic components in the circuit.

Key Features of the TVR 14101 Metal Oxide Varistor (MOV):

1. Surge Protection:
   • MOVs are designed to protect circuits from high-voltage transients. The TVR 14101 is specifically designed for use in situations where electronic circuits may be exposed to voltage spikes that could potentially damage components.
2. Voltage Clamping:
   • The TVR 14101 effectively clamps high voltage surges to a safe level, thereby preventing the connected components from experiencing excessive voltage that could cause permanent damage.
3. Current Rating:
   • It can handle significant surge currents and dissipate the energy from transient spikes.
4. Metal Oxide Composition:
   • MOVs are made from metal oxide material, which gives them the ability to absorb high-energy transients and redirect the surge energy to the ground.
5. Fast Response Time:
   • MOVs like the TVR 14101 have a fast response time, reacting in nanoseconds to voltage spikes, ensuring that your circuit is protected in real-time.
6. Bidirectional Protection:
   • The TVR 14101 is capable of providing bidirectional protection, meaning it can protect against voltage spikes in both positive and negative directions.

Typical Specifications for TVR 14101:

Though the exact details for TVR 14101 may vary depending on the manufacturer, here is a general breakdown of typical parameters for MOVs:

• Maximum Continuous Voltage (Vc): This is the maximum voltage that the MOV can withstand without damage. For the TVR 14101, the typical value might be around 14V (based on common MOVs with similar naming conventions, but you should confirm this in the datasheet).
• Clamping Voltage (Vc): When a transient voltage occurs, the MOV will clamp the voltage at a certain level. This is typically specified as the clamping voltage which can range anywhere from 30V to 200V, depending on the application and the MOV’s design.
• Energy Absorption (J): The TVR 14101 can absorb transient energy, typically rated in Joules. This value indicates how much energy the MOV can absorb before it starts to degrade or get damaged.
• Peak Current (Ipp): The maximum surge current the MOV can handle before it fails or degrades. For example, an MOV might be rated to handle 5,000 A or higher for a short duration.
• Response Time: MOVs have a very fast response time to transient voltages, typically in the nanosecond range.
• Operating Temperature Range: MOVs typically operate in a temperature range of -40°C to +125°C, but you should always check the exact temperature range in the datasheet to ensure proper operation in your environment.

Applications:

1. Power Supplies:
   • MOVs like the TVR 14101 are used in power supply circuits to protect against voltage spikes caused by lightning strikes, power line crosses, or switching events.
2. Surge Protection Devices:
